Legend colours in Map & Tree Map not matching

When I select the category "professional, scientific and technical services", the map returns the results in green while the tree map next to it shows it in orange. I noticed that the colours are all automatically chosen and always random; is there a way I can get different visuals to have a matching colour scheme? I have about 30 different categories so manually selecting colours for all 30 seem a litle cumbersome and not sure if it would even make sense (what if the colours I chose are very similar to each other e.g. 1st ranked category being red, and 2nd ranked category being light red etc.). Thanks for your help
